* Fix CI read-only cache returning stale files on EROFS

When the HF Hub cache is on a read-only filesystem (EROFS), the
hf_hub_download call obtains the new commit hash from the Hub but
then hits EROFS when writing the new snapshot pointer. This error
was silently swallowed by the cached_files recovery block, which
returned the old stale file instead of re-raising.

Fix: explicitly re-raise OSError(EROFS) before the recovery block
so the conftest _with_tmpdir_cache_fallback decorator can catch it
and retry with a writable tmp cache directory.

Also add call-stack logging to the CI fallback handler and wire up
the memory_tracker_plugin in pytest_plugins.
